ICSE

Between the two, it would be ICSE. But, CBSE board is truly a good option, if you are seeking to attempt exams held by Centre. CBSE books (NCERT) form the basis for such exams and NDA exam paper is made from these books.

Both doesn't make a big difference so you can choose anyone. And for a second thought my recommendation is CBSE over ICSE.

Firstly, it depends on your interest whether you want to prepare for IITs or have interest in other fields like BBA. So, find the college according to your interest.
